To l1f/ZZ whom t may concern:

Be it known that we, JOHN ROBERT TOP- Liss and JOSHUA ALEXANDER KAY, subjects of the Queen of Great Britain and Ireland, both residing at Melbourne, in the Colony of Victoria, Australia, have invented Improvements in Machinery or Apparatus for Grooving or Nicking Printing-Type, (for which we have obtained Letters Patentin Great Britain, NO.10,00S, dated June 2S, 1890,) of which the following is a specification.

This invention has reference to the constructionof machinery or apparatus by which the combinations of grooves or nicks required in printing-type, especially for type for use in automatic distributing machines or appliances, can be cut with speed and exactitude and also with the least liability of fracturing or otherwise damaging the type-characters. For this purpose one or more rotary saws or cutters (hereinafter referred to as cutters) is orare used, each fixed upon a shaft provided with suitable driving mechanism and mounted to rotate in a frame or head-stock provided with suitable mechanism for accurately adjusting its position in a transverse direction to a bed or guide upon which a carriage, table, or carrier (hereinafter called a i a suitable stand, is provided on one side with i a centrally-arranged transverse frame 1*,y that carrier) for carrying the type to be cut or nicked 1s arranged to travel. This carrier, which is arranged to move in a longitudinal direction beneath the cutter or cut-ters, can

be made adjustable in height and be provided with means for readily clamping thereon type to be cut or nicked, and for afterward readily nnclamping the same.

In the accompanying drawings, Figure l is a back elevation, and Fig. 2 a plan, of part of a type grooving or nicking machine constructed according to this invention. Fig. 3 is an end elevation, partly in section, of the machine.

1 is a bed-frame formed with longitudinal guides or projections 2, between which slides a carrier 3 for carrying the type to be cut, which is placed side by side in a row, with that edge uppermost that is to be grooved or nicked. This carrier is so constructed that it can be raised or lowered according to the depth of cut required and to suit different Sizes of type. For this purpose the carrier is shown made in two parts 3 3a, as shown, the

Vunder side of the upper part 3 being made rier may be arranged to slide upon its bed by I pressure directly applied to it or suitable ineg chanical means may be provided for causing it to reciprocate along its bed. In the exam- ,ple shown the carrier is provided with a n-u-t 6, made in two parts, each pivoted to thelower l part 3ft of the carriage and provided with an i arm 6% 7 is a longitudinal screw-shaft carried by Ithe bed-frame 1 and provided with a driving-pulley 8.

By bringing the arms 6 tol gether the two parts of the nut can be caused j to engage the screwshaft, upon which they can be held by causing a link 6, hinged to one of the arms 6, to engage the other arm.

9 is a spring placed between the arms and adapted to press them apart and disengage. the two parts of the nut from the screw-shaft 3" when the link 6b is turned to disengage the arms from each other.

The bed-frame l, which may be mounted on carries in suitable guides a number of inov able head-stocks 9, in each ot' which rotates a spindle 10, each provided with a pulley 11 and having one end arranged to overhang the bed-frame l to a suficient distance to carry a rotary cutter l2. The number of cuti ters employed will depend upon the number of grooves or nicks desired in any combination. In the example shown three head-stocks with cutters are used; but the transverse frame l is shown as made to carry four headstocks, the bed for the fourth being shown at the right-hand side of Fig. 2. Each head-stock is provided with an adjusting-screw 13, by

means of which it is held in position and by which it can be moved backward or forward to any desired extent in a direction transverse to the bed frame. This screw is mounted to rotate in an extension 9a of the head-stock and -to work through a fixed nut 14, carried by the transverse frame la;

IOO

This nut may with advantage be of white inetal cast between projecting portions 1b on the transverse frame 1f. Each adjustingscrew 13 is fitted with an adjustable disk 15, formed with a notch 1G (or it may be with two or more notches, recesses or holes) to receive a spring-catch 17 that is pivoted to the extension 9a. Each catch serves to govern the turning movement of its corresponding adj usting-screw and to hold the screw and attached parts stationary when it is engaged with the disk.

1S is a nut, between which and a collar 19 the disk 15 is normally fixed, so as to be fast with the adjusting-screw. This screw is prevented from moving endwise by the collais 19 19, which are fast thereon and bear at opposite sides of the extension 9a.

Each head-stock has anindeX-tinger 20, adjacent to which is a bracket 2l, having on its upper side a scale 21 to indicate the number ot' turns to be given to the adjustingserew 13 to move the head-stock to any required extent.

The row of type to be operated upon is held in position longitudinally by straight bars 22, having lips or flanges 22, which overlap the type and keep the same from rising. The row of type is held endwise between two strips 23 of such height as to allow clearance for the cutters. To facilitate the ready adjustment of type in position, one of the hanged sidebars 22 and one end strip 23 are made removable, and eccentric-cam levers 24 are provided pivoted to the upper part 3 ot the carriage for quickly clamping and unclamping the said bar and strip.

The operation of the machine is as follows: The several nuts 18 are first turned so as to release the disks 15, and the adj usting-screws 13 are rotated to move the head-stocks toward the bed-frame 1 until all the cutters are in the same plane and overhang one end of the type to a suieient extent. Each nut 1S is then tightened against its disk 15, care being taken that the corresponding catch 17 is in the notch 16 of its disk 15. Each rotary cutter requiring to be moved forward can now be placed in position by adjusting its headstock by means ot' its screw 13, the index 2O and scale 21 indicating how many turns of the adj usting-screw are necessary to advance the cutter sufficiently to agree with the arrangement of nicks to be cut as determined by a nicking-chart. By liftingthe pivoted catch 17 out of the corresponding disk-notch 1U and giving one or more full turns to the respective adjusting-screw 13, the relative arrangement ot the nicks can be Varied. The carriage 3 3" is then made to travel underneath the cutters, which then effects the nicking process. Then this is done, the eccentric cam-levers 24E are turned to release the side bar 22 and end strip 23, the cut type is removed, and the carrier returned to its normal position to be refilled with type, which after being clamped up is cut by again moving the carrier forward below the cutters, as before. Then the carriage is driven by power, the split releasing-nut 0 should be disengaged as soon as the row ot type has passed from under the cutters, thus stopping the movement of the carrier but allowing ot' the rotation of the screw-shaft 7.

As will be obvious, instead of making the bed 3 3" endwise movable, it may be fixed, the type to be grooved or nicked being then pushed over to its upper surface and oelow the cutters.
